A.Word.A.Day--lipogram

In spite of what it sounds like, a lipogram is not a message with a kiss.
Lipogram is a work written with a constraint.

Imagine you've just started your great epic novel and one of the keys on
your keyboard is broken. It would be trivial to manage without a Q, X,
or Z, but writing without a single E -- ah, that'd be some challenge. If
it sounds undoable, consider that whole books have been written without
an E, the most used letter in the English language. Without an E, one has
to give up some of the most common pronouns such as he, she, we, me, and
so on. What's more, even the article "the" is barred.

Coming back to books written without Es (I'm sure writing them is not
something everyone can do with ease), Ernest Vincent Wright's 1939 novel
Gadsby is written without the second vowel. One of the best known E-less
works is Georges Perec's lipogrammatic French novel, La Disparition (The
Disappearance). Its plot is full of wordplay, puzzles, and other word-fun.
For example, a character is missing eggs, or is unable to remember his
name because it needs E in the spelling.

Though it may be hard to believe considering the restriction under
which it is written, the novel is said to be quite engrossing. Apparently,
many reviewers were not even aware that a special constraint was used in
writing it. After writing the novel, Perec faced a protest from the A, I,
O, and U keys on his keyboard that they had to do all the work and E was
leading an e'sy life. So Perec had no choice but to write a short work
called Les Revenentes, where he put to work all those idle Es: the only
vowel used was E.

If that doesn't sound incredible enough, here is more. La Disparition has
been translated into English as "A Void" by Gilbert Adair. Of course, the
translation also doesn't have any E in it. In case you have not already
noticed, both the phrases "La Disparition" and "A Void" have only vowels
A, I, and O in them, same as in the word "lipogram". And Void's protagonist
is named Anton Vowl.

One can write numbers from zero, one, two,... onwards, and not use the A
key on the keyboard until reaching thousand. As for the literary merit of
that composition, I'm not very certain.
